   "However a patent [2]unearthed by Twitter user @Underfox3 has found
   that the company could well be developing a plan: stacking transistors
   on top of each other for better performance in less space. Now, of
   course, this is only a patent – companies patent weird and whacky
   things all the time for a variety of reasons, most likely to prevent
   competitors from getting the jump on them. "

   "But there is something interesting about Intel thinking its way around
   the problem of how to squeeze more power into ever-smaller spaces -
   namely, if this design comes to fruition, Intel could be looking at
   sub-2 nanometer (nm) processes."
